Hi
I am using the new TimeBar control to display data loaded from the database via RIA. When I set the date values manually in XAML the TimeBar renders correctly, however when I use the binding to the view model the TimeBar does not render.
The server call does take a few seconds to return but it should still work.
I have tried the assemblies from the previous official release as well as the latest internal build (2011.1.613.1040)
This works
This does not
ViewModel
Any ideas?
